Gates 33963 Heavy-Duty Engine Coolant Thermostat

Gates never fails me!

A good price and on time. It works like it's supposed to.

This works great for my suburban and was so easy to install. It has maintained the proper temperature and fit exactly as it should. I replaced this when I replaced my radiator, so far so good with no problems. I would recommend it.

The unit i received is different from the pictures. It is still branded gates so i dont know if its authentic or not. I was hesitant to put it in but it did open at the correct temperature pretesting on a bench, as well as on the vehicle. The rubber gasket seemed a tiny bit loose/oversized and wouldnt fit in the thermostat housing until i pressed it in with my fingernails. The old gasket had a perfect fit. Giving it 4 stars for now.

When I changed the water pump on my Tahoe I changed the thermostat at the same time. No complaints.

Gates is a good product

I would use this any day to replace an original equipment thermostat without hesitation. Unit installs very easily and came with gasket needed to finish project. However, the a c delco thermostat did not come with the gasket. That is why about the gates. Works great no problems.
